These markets evaluate how long a specific tennis match at the 2026 US Open will last by counting the total number of games played. Each market has a different threshold for the total games, determining whether the match was longer or shorter than expected. Outcomes are based on the official match result, with special provisions for cancellations, delays, or retirements.
The markets determine whether the total number of completed games in the Marin Cilic vs Andrey Rublev professional tennis match at the 2026 US Open Men Singles Round Of 128 exceeds specified thresholds of 32.5, 37.5, or 42.5 games. If the match does not occur before play begins—due to injury, walkover, forfeiture, or other cancellation—the markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with resolution within two weeks after completion. If a player retires during the match, markets that can be settled based on completed play will resolve accordingly, while unresolved markets will settle at a Fair Market Price determined by the Exchange.
